Answer:
1). For < 4 Coordinates will be A"( -2,2),B"(1,-1),C"(-3,-2).
For 1 > Coordinates will be A"(3,2), B"(6,-1), C(2,-2).
2). A"(-2,2), B"(-1,-2), C"(-5,-1).
Explanation:
1) In this part of the question we have to find the new coordinates of the triangle when there is a shift of 4 in left means the new coordinates will be A"( 2-4,2),B"(5-4,-1),C"(1-4,-2) Or A"( -2,2),B"(1,-1),C"(-3,-2).
And when shifted by 1 in right direction A,B,C will be A",B",C" that are A"( 2+1,2),B"(5+1,-1),C"(1+1,-2) Or A"(3,2), B"(6,-1), C(2,-2).
2) Now we have to get the reflection of points A(2,2), B(5,-1), C(1,-2) across Y axis.
When A reflects about Y axis it will reflect in Second quadrant. So new coordinates will be A"(-2,2).
Similarly B and C will reflect in third quadrant. So new coordinates will be B"(-1,-2) & C"(-5,-1).
